Flying home to Singapore from Hanoi on SQ175, our expected arrival time was 1737. However, 30 minutes before landing, the captain informed us that there was a huge thunderstorm over Changi and we would be unable to land, and therefore had to go into a holding pattern. We finally landed at 1820 hours, but not before I managed to get a picture of the storm on final approach as it was moving away from the airport with the setting sun breaking through [Nikon D200]
